Abstract: A roll unwinding device, especially for a printing machine, possesses clamping sleeves (23) having tapering end sections (41). The carrier receiving the roll (2) is freely movable, at least to a degree of horizontal freedom of movement, so that an automatic alignment of the core with the clamping sleeve takes place when the clamping sleeves (23) are introduced in the core. In the vertical direction, the force exerted by the tapering end section (41) can be determined by a force measuring device and be used for adjusting a lifting device. The height of the roller carrier can also be adjusted while the clamping sleeves are loaded in the direction of introduction. This permits a simple automatic alignment. <IMAGE>

Abstract: In determining the ratio of ammonium cpds. to dissolved NH3, the water sample from a closed container with separate inlets/outlets for liq./gas and for reaction media, the water is conveyed by compressed air into a test-cell operated at 10-50 deg.C. In addn. to temp. measurement and control units, the cell has a sensor for NH3 gas from the water, brought by alkali metal hydroxide to a pH of 10.5 or more. Sample and gas are transferred through multi-way valves by a suction/pressure pump subject to a micro-processor. Values from the sensor are compared with calibration curves derived from samples with known NH4/NH3 ratio.

Abstract: A digital mask image is obtained by emitting radiation onto a subject before a contrast medium is injected in a blood vessel, and digital mask image data corresponding to the mask image is stored in a first image memory (24). A digital contrast image is obtained by emitting radiation to the subject after the contrast medium is injected in the blood vessel, and contrast image data corresponding to the contrast image is stored in a second image memory (26). The mask image data is read out from the first image memory (24) and the contrast image data is read out from the second image memory (26). Then, the mask image data is subtracted from the contrast image data by a subtraction circuit (28), thus obtaining angiographical image data. Edges of the blood vessel are detected from the angiographical image data by an edge detecting circuit (30). Edge image data corresponding to the detected edges is added to the fluoroscopic image data by a summing circuit (34), thus obtaining a road map image including a contour of the blood vessel and the fluoroscopic image. The road map image is displayed on a TV monitor (38).

Abstract: An image transducing apparatus is disclosed. An object to be imaged is located in a fixed object plane. A lens focuses the image of the object upon an imaging plane. A photoelectric transducing array having a plurality of congruent, discrete, spaced-­apart transducing elements arranged in an array is located in the imaging plane and provides an electrical signal representative of the light intensity thereon. The photoelectric array is movable on a microstage which is movable in two axis. The microstage is mechanically displaced in a direction parallel to the imaging plane from a first position to a plurality of subsequent positions. The distance from each position to a subsequent position is less than the dimension of a transducing element along the direction of the displacement. The photoelectric array is moved and is stopped at each of the displaced positions where an electrical signal from the photoelectric array is taken. The signals from each of the positions traversed by the photoelectric array is combined to form an electrical representation of the image of the object.

Abstract: A signal processing apparatus for reducing the quantisation noise by using two or more so-called noise shaping circuits (14a, 14b), is disclosed. The input signal may be audio or video signals. One of the noise shaping circuits (14a) is supplied with a signal which is the relative addition of the input signal and the dither while the other noise shaping circuit (14b) is supplied with a signal which is the relative subtraction of the input signal and the dither. The signal components of the outputs of the noise shaping circuits are effectively combined together to cancel the dither components to produce an output with an improved S/N ratio. A plurality of such signal processing apparatus may also be arranged in parallel (see figure 5), in which case different dithers are used in the respective signal processing apparatus and the outputs of the respective signal processing apparatus are combined to further improve the S/N ratio.

Abstract: The movements of a ball in a steel tray are shown on a screen, which makes it possible to work out in which number the ball will finally arrive and more particularly before a ring mounted in the tray is crossed. The capability consists in the fact that the path shown on the screen and the associated numbers can be ascribed to a system, as a result of which it can be worked out very easily that, from a given number combination and speed, it follows that the ball will finally arrive in a given number. The quicker a person calculates and reacts, the easier and more precisely he will arrive at the result presupposed by the computer.

Abstract: At least one slit (4a, 4b) having a predetermined shape is formed around a contact region of a lower wiring layer (1) formed on a substrate (5), and insulating portions (6a, 6b) formed integrally with an insulating layer (6) is embedded in these slits (4a, 4b). This insulating layer (6) is formed on the lower wiring layer (1) and has a contact hole (3) located at a position corresponding to the contact region. Since the insulating portions (6a, 6b) as a wedge-like portion project into the slits downwardly from the rigid insulating layer (6), positional errors caused by thermal expansion of the lower wiring layer (1) in annealing of the upper wiring layer (2) can be suppressed, and an abnormal geometry such as a projec­tion on the upper wiring layer (2) can be prevented. In addition, a semiconductor device free from inter­wiring short-circuiting and excellent in flatness can be obtained.
